Images that I mapped to an object won't show up when I render the image
An object that is UV-unwrapped will show the UV-mapped image in texture mode in a 3d-view. If however the object hasn't had a material and texture assigned to it, the image or texture wont be rendered, as seen in first image.



Add a material to the object, then a texture to the material. Choose "image or movie" and open the image. Set Mapping to UV and choose the UV-map.
